the chair or stool is at all times free to be shifted longitudinally ofthe rod 31, and the guide sleeve 42 cannot separate from the rod 31, byvirtue of the-shoulder 38 and collar 39. v V l The operation of the seator stool is as follows: When the ring is applied to the pedestal Hi, theauxiliary seat or chair may be shifted or swung circumferentially of thepedestal ID, in either direction, by the operator sitting upon the seatelement 23 and engaging the floor with his feet. The casters are free toturn horizontally and renders this operation easy. The operator mayshift the chair or stool generall radially toward or from the pedestalill of the barber chair, by engaging the floor with his feet, whileseated upon the seat element 23. This action is permitted by the factthat the guide sleeve 42 is permanently slidable upon the rod 31. Thespring or springs 34 will yield to permit of this adjustment. Thesesprings will return the chair or stool to the normal position when theweight is removed therefrom. v

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatvarious changes in the shape, size, and arrangement of parts, may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims. 7

Having thus described my invention, what I claim is: V

1. An auxiliary chair or stool for use in co nection with a barber chairhaving a pedestal, comprising a frame including a triangular group ofupstanding upwardly converging legs connected at theirupper ends, a seatelement secured to the upper ends of the legs, casters secured to thelower ends of the legs, a substantially vertical tube arranged'centrallyof the triangular-group of legs, a' horizontalguide sleeve secured tothe lower end of the substantially vertical tube, a substantiallyhorizontal rod permanently slidably mounted within the guide sleeve,springs to oppose the longitudinal movement of the guide sleeve andreturn the same to the normal posi-.

tion when released, such springs being connected attheir inner ends tothe guide sleeve and at their outer ends to the substantially horizontalrod, and a ring mounted upon the pedestal and connected with thehorizontal rod. I

2. An auxiliary chair or stool for use in connection with a barber chairhaving a pedestal, comprising a frame including a triangular group ofupstanding legs, a seat mounted upon the upper ends'of the legs, wheelssecured to the lower ends of the legs, a substantially vertical'tubearranged centrally of the triangular group of legs, a horizontal guidesleeve secured. to the lower end of the substantiallyvertical tube, asubstantially horizontal rod permanently slidably mounted within theguide sleeve, pins connected with the substantially horizontal rod anddisposed upon opposite sides of the guide sleeve, a pin secured to theguide sleeve, and retractile coil springs secured to the pins of thesubstantially horizontal rod and to the pin of the guide sleeve, and aring mounted upon the pedestal and connected with the substantiallyhorizontal rod,

3. An auxiliary chair or stool for use in connection with a barber chairhaving a pedestal, comprising a frame including a triangular groupvofnpstanding legs, a substantially vertical tube secured to the upperends of the legs and internally screw threaded, a substantially verticalscrew engaging within the screw threaded tube, a seat element mountedupon the screw, longitudinally adjustable leg extensions having screwthreaded engagement with the lower ends of the legs, wheels carried bythe leg extensions, a horizontal guide sleeve secured to the lower endof the substantially vertical tube, a substantially horizontal rodpermanently slidably mounted within the guide sleeve, retractile coilsprings extending longitudinally of the substantially horizontal rod,means attaching the inner ends of the springs to the guide sleeve, meansattaching the outer ends of thesprings to the substantially horizontalrod upon opposite sides of the guide sleeve, and a ring to be mountedupon the pedestal and connected with the substantially horizontal rod.

4. An auxiliary chair or stool for use in connection with a barberchairhaving a pedestal, comprising a frame including a substantially verticaltubeand a plurality of downwardly diverging legs secured to the upperendof the tube and forming a group surrounding the tube, the legs extendingdownwardly below the tube and the tube being arranged centrally of thegroup and having its lower end terminating near the floor, casterssecured to the lower ends of the legs, an elongated generally 7 radialhorizontal guide member, means to pivotally mount one end of the guidemember upon the pedestal so that the guide member is free to swingsubstantially horizontally in opposite directions, an element secured tothe lower end of the vertical tube and slidably engaging the elongatedguide member and permanently free to be shifted longitudinally of theguide member withinlimits, means to positively limit the outwardmovement of the element with relation to the elongated guide membersothat the element and guide member cannot be separated, a retractilecoil spring arranged exteriorly of the guide member and beneath and insubstantial vertical alignment with the guide member to be coveredthereby and having one end attached to the slidable element and itsopposite end attached to the guide member, a seat, and a rod carryingthe seat and adjustably mounted in the upper end of the vertical tube sothat the seat may be raised and lowered.
